Overview

... Components Positive Voltage Protection Negative Voltage Protection High Current Drive Output for SCR Precision Voltage Reference for 5V/12V Outputs Power Good Signal Generator with Hysteresis Description The KA3501 is complete housekeeping circuits for use in the secondary side of SMPS(Switched Mode Power Supply).
This IC(Integrated Circuit) contains a precision voltage reference, protection circuits and a power good signal generator.
It also has a high current drive output for use in conjunction with an external "crowbar" SCR.
The reference voltage is trimmed to ±2% for correct output voltages(+5V/ +12V) and power good signal generator is to monitor the voltage level of power good supply ...
